I am using a DJI Phantom 4 Pro Plus with GL300C Version B controller and Lenovo M8 Gen 2. When I create a mission, it will successfully upload to the drone but the drone will not takeoff. Pressing the takeoff button just loops back to the mission map. If I move the drone to within the boundaries of the mission which is very close by- 20 m to the start point, the drone will launch. This is not very practical for commercial mission of the type that I do.

I've had the same behavior from Pix4D capture
